This review discusses recent trends in non-surgical cosmetic dermatology procedures in the United States and reports no new clinical results, emphasizing the need for evidence-based evaluations of safety and efficacy.

In this study, an ethanol extract of Crinum asiaticum was observed to significantly increase hair-fiber lengths and promote hair growth in rat vibrissa follicles and C57BL/6 mice.

This review summarizes the enhanced absorption and bioavailability of phytosome delivery systems, which combine herbal extracts with phospholipids to improve therapeutic potential, and provides an updated overview of their development, commercial availability, and patented technologies.

This study reported that four patients with lichen planopilaris showed dramatic improvement, including symptom reduction and hair regrowth, after treatment with low-level light therapy.

This study found that finasteride decreases melanin levels in melanocyte and melanoma cells by inhibiting MC1R, without causing cytotoxicity, suggesting its potential role in regulating melanogenesis.

This study found that β-catenin is essential for hair follicle stem cell proliferation and may regulate this process through the PI3K/Akt pathway, suggesting its potential as a therapeutic target.

This study found that red ginseng oil promoted hair growth and protected against UVC-induced skin damage in mouse models.

This study found that berry extracts, especially black raspberry extract, may have anti-aging effects due to their high antioxidant activities.

This study developed rat monoclonal antibodies that specifically detect Pax1/PAX1 protein, which could improve diagnostic protocols for conditions involving deregulated Pax1/PAX1 expression.

This study suggests that dermal stem/progenitor cells can be enriched by intracellular granularity and display high proliferation and differentiation potential in vitro, distinguishing them from other fibroblasts and progenitors.

This study found that intrauterine administration of botulinum toxin A improved endometrial environment and receptivity in a murine model of thin endometrium through mechanisms involving IGFBP3 and osteopontin.

This study suggests that dutasteride may be more beneficial than finasteride for therapeutic or preventive use.

This study suggests that finasteride treatment may improve pulmonary immune response in mice following trauma and sepsis, indicating potential as a therapeutic option after major trauma.

This study found that L-cystine, D-pantothenat, and miliacin can enhance the metabolic capacity and proliferation of human keratinocytes, with a combination of these additives potentially providing synergistic benefits in growth media.

This study found that systemic administration of NDP-MSH, a melanocortin receptor agonist, provided neuroprotective effects on dopaminergic nigrostriatal neurons in a mouse model of Parkinson's disease, reducing neuroinflammation and suggesting a role for regulatory T cells in these neuroprotective effects.

This study suggests that using growth factors and ADSC-conditioned medium can enhance keratinocyte viability and migration in epidermal transplantation, potentially improving chronic wound healing rates with a patient-dependent effect.

In a comparative genomic study, researchers observed significant genetic differences among the three chemical races of the alga Botryococcus braunii, leading them to propose reclassifying these races as distinct species based on their unique genomic characteristics.

This study on feather pattern formation in chicken skin found that inhibiting gap junctional intercellular communication can lead to the emergence of new feather buds in specific spatial patterns, suggesting that GJIC may facilitate Turing-type periodic patterning by propagating inhibitory signals over long distances.

This review discusses the role of extracellular vesicles from specific skin cells in wound healing, emphasizing their potential in regenerative medicine and reporting no new experimental results.

This study demonstrates that Tp63-expressing epithelial stem cells from non-skin tissues can respond to skin morphogenetic signals and contribute to the formation of hair follicles, sebaceous glands, and epidermis.

This review covers nonsteroid-based therapies for alopecia areata, finding potential in PRP, UVR, and laser treatments, but highlights a lack of high-quality evidence for their efficacy.

This study reported that the n-butanol fraction of Perilla frutescens extract, particularly rosmarinic acid, showed potential for hair regrowth and anti-androgenic activity in male mice, suggesting it as a possible treatment for androgenetic alopecia.

This study found that transtherapy, a treatment using Korean medicine, significantly improved acne scars, reducing the scarring grade from an average of 3.5 to 1.5 in moderate and severe cases.

This study found that bulge-derived keratinocytes from human follicles were more resistant to differentiation compared to epidermal keratinocytes, possibly due to WIF-1 involvement.

The author reports that using Total Excision Techniques in hair transplant surgeries increased graft yield by at least 50%, with minimal scarring in the donor area.

This study found that lncRNA-599547 positively regulates the expression of the Wnt10b gene by interacting with miR-15b-5p, enhancing the inductive property of dermal papilla cells in cashmere goats.

This study suggests that Eclipta prostrata may promote hair growth in mice and human dermal papilla cells through regulating FGF-7 and mTOR signaling.

This study reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.

This study found that BeauTop, a supplement containing several traditional Chinese herbs, may promote hair growth in mice with alopecia, potentially by modulating EGF and FGF-7 levels.

This case report describes an 80-year-old patient whose scalp wound healed by secondary intention, with unexpected hair regrowth observed at 180 days, suggesting hair neogenesis is possible even in older adults.
